• Electronic Precise Temperature Control Proportioiiiil (or PID) controller with Pt sensor and non-contact relay, performs accurate operation within ± 0.5°C control accuracy. • Unique Slide-Shutter System Specially precise and uniform temperature distribution is realized by this unique system, together with one or two strong large fan and exhaust-damper which can control suitable air exhaust from the oven. The slide-shutters are set on the left and right side whole wall of inner chamber, and can control finely hot air inlet-outlet, (cf. next page) • Big Capacity Models with High Operation Efficiency You can choice reasonable model among six models from 80 cm wide (384/) to big 250 cm wide (4,500/). • Operation-Start is One-Touch Operation starts by your one-touch of the start-button. You can select timer (24 hours) operation or continuous operation by the selector switch. Also optional model with program- controller is prepared. • Safety System Reliable operation safety system — overheat protector independent of main controller, safety system for fan-motor over load, or slight leakage and short circuit breaker, etc. • Optional Specifications are acceptable Special size, temperature range (max. 500°C), with program controller, with temperature recorder, with observation window, with inner light, or with micro filter etc.
